Introduction: Over the past few decades, psychotherapy research was dominated by testing the efficacy of "brand name" therapeutic techniques and models. Another line of research however, suggests that common factors, such as the therapeutic alliance and empathy, might play a greater role in effective therapy than specific therapeutic techniques and models. Routine process monitoring (RPM), focusing on common factors, has emerged as a promising approach to enhance therapy outcomes.

The formation of biomolecular condensates in vitro and in vivo has become an increasingly important subject of studies. One particular area of interest is the phase separation of chromatin in the nucleus. However, the interplay of condensed chromatin and chromatin-binding enzymes has barely been studied as of now.

A physical perspective on lithium therapy.

Prog Biophys Mol Biol

December 2024

Lithium salts have strong medical properties in neurological disorders such as bipolar disorder and lithium-responsive headaches. They have recently gathered attention due to their potential preventive effect in viral infections. Though the therapeutic effect of lithium was documented by Cade in the late 1940s, its underlying mechanism of action is still disputed.

Schizophrenia is accompanied by significant cognitive impairments, which often persist to a relevant extent after remission of clinical symptoms and has a negative impact on psychosocial functioning. These impairments are often experienced as very stressful by those affected. Under the umbrella term of Cognitive Remediation Therapy (CRT), evidence-based therapy options are available that improve both the respective cognitive target functions and the psychosocial functioning.

Noninvasive brain stimulation (NIBS) has been increasingly investigated during the last decade as a treatment option for persons with autism spectrum disorder (ASD). Yet, previous studies did not reach a consensus on a superior treatment protocol or stimulation target. Persons with ASD often suffer from social isolation and high rates of unemployment, arising from difficulties in social interaction.

How chromatin enzymes work in condensed chromatin and how they maintain diffusional mobility inside remains unexplored. Here we investigated these challenges using the Drosophila ISWI remodeling ATPase, which slides nucleosomes along DNA. Folding of chromatin fibers did not affect sliding in vitro.

Although impairments in social cognition are a core feature in schizophrenia, the relationship between its subcomponents is less clear. Nineteen schizophrenia patients and 20 matched healthy controls were tested for emotion recognition, and for the cognitive and affective subcomponents of empathy and theory of mind (ToM). Patients scored significantly worse than controls on cognitive empathy and both subcomponents of ToM.

Specialized psychotherapeutic treatments like dialectical behavioral therapy (DBT) are recommended as first treatment for borderline personality disorder (BPD). In recent years, studies have emerged that focus on repetitive transcranial magnetic stimulation (rTMS) in BPD. Both have independently demonstrated efficacy in the treatment of BPD.

Introduction: While lithium (Li) has been well established for the treatment of bipolar disorder, geriatric patients require special attention when it comes to issues of drug safety. Declining renal function, amongst other medical conditions, and polypharmacy may pose increased risks. Only a few previous studies have addressed the management of Li in geriatric patients.

Background: Transcranial direct current stimulation (tDCS) has been proposed as a feasible treatment for major depressive disorder (MDD). However, meta-analytic evidence is heterogenous and data from multicentre trials are scarce. We aimed to assess the efficacy of tDCS versus sham stimulation as an additional treatment to a stable dose of selective serotonin reuptake inhibitors (SSRIs) in adults with MDD.

Unlabelled: Patients with schizophrenia often have cognitive impairments that contribute to diminished psychosocial functioning. Cognitive remediation therapy (CRT) has proven efficacy and is recommended by evidence-based treatment guidelines. Important moderators of efficacy include integration of CRT into a psychiatric rehabilitation concept and patient attendance at a sufficient number of therapy sessions.

Background: Delirium tremens (DT) is a common complication of alcohol withdrawal. Pharmacological treatment of hospitalized patients with DT is important in addiction medicine but also in other medical disciplines where DT can occur as a complication of hospitalization. Patients suffering from DT require treatment with benzodiazepines (short-acting benzodiazepines for elderly patients to reduce accumulation), and in cases of psychotic symptoms, treatment with antipsychotics.

The COVID-19 crisis impacts populations globally. This impact seems to differ for groups with low- and high-socioeconomic status (SES). We conducted a qualitative study in the Netherlands using a salutogenic perspective to examine experiences with stressors and coping resources during the pandemic among both SES groups to gain insight on how to promote the health and well-being of these groups.

The Joles Jewish Hospital in Haarlem (a small city in the Netherlands) was established in 1930 to provide a Jewish milieu for local patients. Mozes Joles, a wealthy Jewish businessman, bequeathed his fortune to the Haarlem Jewish community to accomplish this objective, and its spiritual leader, Rabbi Simon Philip de Vries, was the driving force in successfully achieving this goal. The Joles Hospital was forcibly closed by the Nazis in 1943, and the postwar leadership of the Haarlem Jewish community decided not to reopen it.

Social interaction difficulties are a hallmark of psychotic disorders, which in some cases can be definitely traced back to autoimmunological causes. Interestingly, systemic and intrathecal inflammation have been shown to significantly influence social processing by increasing sensitivity to threatening social stimuli, which bears some resemblance to psychosis. In this article, we review evidence for the involvement of systemic and intrathecal inflammatory processes in psychotic disorders and how this might help to explain some of the social impairments associated with this group of disorders.

Background: Although clinically effective treatment is available for schizophrenia, recovery often is still hampered by persistent poor psychosocial functioning, which in turn is limited by impairments in neurocognition, social cognition, and social behavioral skills. Although cognitive remediation has shown general efficacy in improving cognition and social functioning, effects still need to be improved and replicated in appropriately powered, methodologically rigorous randomized controlled trials (RCTs). Existing evidence indicates that effects can most likely be optimized by combining treatment approaches to simultaneously address both social cognitive and social behavioral processes.

Background: Evidence about the impact of the COVID-19 pandemic on existing health inequalities is emerging. This study explored differences in mental health, sense of coherence (SOC), sense of community coherence (SOCC), sense of national coherence (SONC), and social support between low and high socioeconomic (SES) groups, and the predictive value of these predictors for mental health.

Participants And Procedure: A cross-sectional study was conducted using an online survey in the Netherlands in October 2021, comprising a total of 91 respondents ( = 41, low SES; = 50, high SES).

Single-molecule force spectroscopy using optical tweezers continues to provide detailed insights into the behavior of nanoscale systems. Obtaining precise measurements of their mechanical properties is highly dependent on accurate instrument calibration. Therefore, instrumental drift or inaccurate calibration may prevent reaching an accuracy at the theoretical limit and may lead to incorrect conclusions.

Introduction: Non-invasive brain stimulation techniques such as repetitive transcranial magnetic stimulation (rTMS) offer a promising alternative to psychotherapeutic and pharmacological treatments for depression. This paper aims to present a practical guide for its clinical implementation based on evidence from the literature as well as on the experience of a group of leading German experts in the field.

Methods: The current evidence base for the use of rTMS in depression was examined via review of the literature.
